漢字古今音資料庫 is a database that gives pronunciations of Chinese character from all Chinese languages! It also shows reconstructed readings of old and middle Chinese from different time period.
From the example in my video, the pronunciation of 業 is
- ȵiap5 in Hakka(Meixian)
- ŋiep5 in Min(Teochew)
- jip22 in Cantonese(Hong Kong)
- iəʔ5 in Wu(Wuhu, Anhui)
